- W2384740807 abstract "In the time domain,a composite inversion procedure is presented to identify the dynamic loads and structural parameters for a structure with limited output observations and unknown input based on sub-structure analysis. Firstly,the structure is decomposed into several sub-structures and the finite element model of the sub-structure with unknown input is built.Its connecting relationship with others is replaced by the interface forces. The forward analysis model of the dynamic load identification is established by Green's function. Based on regularization method,the time history of dynamic load can be stably reconstructed. Then,the finite element model of the global structure is built on the basis of identified dynamic loads,and the structure parameters are identified through nonlinear least squares method. The numerical example indicates that the presented composite inversion is effective and stable for the loads and structural parameters identification with noisy response." @default.
